A single line drawing which defines the outer and inner forms (contours) of people or objects.
a continuous line drawing where the student draws the interior and exterior contours of the subject. In the process, students keep their eyes on the contours of their subject more than they do on their drawing, and the results are drawings that are often randomly abstracted or distorted.
Contour drawing shows the outline of the subject, and not the volume or mass of an object. Blind contour drawings are those created by looking only at the subject, and not the paper while drawing.
